Chapter 5: Installing the HostRAID Controller and Disk Drives ●27

Installing the Controller to a SAS Expander

You can use a SAS edge expander to connect multiple disk drives to your HostRAID controller
or multi ple contr ollers. Commands can be se nt down on e link an d data ret urned on another in
a separate connection to increase fault tolerance. Using a SAS expander and dual-port SAS
drives and SATA drives with 2-port adapters, you can design redundant systems for maximum
fault-tolerance.
To install the HostRAID controller to a SAS expander:
1Using the appropriate cable, connect the HostRAID controller to a PHY connector on the
expander.
2Connect a cable from a PHYconnector on the expander to a disk drive.
